I could'nt find anything wrong with your set up.
Can you measure the resistance between pin 1 and pin 6 also 8 and 5 should measure 350k
if it measures 145k then it is an INA118 the laser trim operator mixed up part of a the batch.
then Rg = 50 ohms G=500 and you have an INA118
It measures 255k ohms between pins 1 and 6, also between 5 and 8
